Decanting process

Liquid from another vessel is poured into the decanter in order to separate a small volume of liquid, containing the

process. In most modern winemaking, the need to decant for this purpose has been significantly reduced, because many wines no longer produce a significant amount of sediment as they age.

Decanting cradles

Baskets called decanting cradles, usually made of wicker or metal, are used to decant bottles that have been stored on their side without needing to turn them upright, thereby avoiding stirring up sediment. These are particularly useful in restaurants, for service of a wine ordered during a meal, but less important at home, where a bottle can be stood upright the day before. More complicated s also exist to facilitate smoothly pouring, without disturbing sediment.

Aeration
